Application filed December 28, 1897. Serial No. 663.934. (No model.)

To au whom, it may concern: lle it known that I, PIERRE J. E. E. CHAM- BOST, a citizen of thc Republic ot' France, residing at ll Runiford street, Liverpool, in the county of Lancaster, England, have invented certain new and useful Improvements in Liquid-Fuel Furnaces, of which the following is a specification.

This invention has been patented in Great Britain, No. 29,000, dated December 17, 1896.

rlhis invention relates to fura aces of steamgenerators and heating-furnaces for burning hydrocarbon liquid of the heavy kinds or of any density.

The invention willv be described with refery ence to the accompanying drawings, which l the improvement.

provided and placed in a setting or retort of brickwork I, with a -narrow space I' around it and with openings r1I at the bottom for the heating gas jets or iiames and other openings il at the top. Above'these are the burners Y,

,l communicating with the cylinders A by the vpipes D E J.

In the interior of the vessels A there is a central screwed shaft B, with its ends centered and supported by the covers a of the cylinders, and on this shaft a number of diaphragm-plates b are supported. mounting these plates b on the screwed shaft any number can be used to suit the quality of oil used and they may be adjusted longitudinally to any position desired. The upper and lower edges of the alternate plates b are cut. away, as shown, to make a zigzag course for the oil-vapors. .The oil is delivered to the cylindersA by a pipe C, which has an automatic controllirug-valve operated as hereinafter describedv and shown in Fig. 3. The cylinders Apareheat'ed'by some of the vapor made in the apparatus,which is burned at the burners G on the pipes H, which are connected with the vapor-supply pipe lD by the pipe F. A drain-cock H is located atthe lower end of pipe F, by which any settlings may be withdrawn. -The heat of Y' the flames of those Aburners G passes through the space 'I, around'the cylinders A, and then out by the passages t" into the furnace proper.

In operation both or one of the vcylinders A may be used at a time; but the pipes D, D', and H, connected with their respective vessels, being provided with cocks d d. and 7L h', respectively, one of the cylinders can be cut oit from 'connection with the pipes E J and the burners Y while the 'other is in action. In either case all the lburners Y are 4always in action; In action, therefore, when one cylinder is in yuse one set of valvesdand 7L or d h would be closed and the' other set, connected with the other vaporizing-cylinder A, open, and assuming the apparatus to be going the bulk of the vapor generated would pass to the burners Y and partly to the burners G. The vapor-flames from the burners G, acting on the cylinder A, passing up around the cylinder A, through the narrow passage under the brick setting'or-lining I, easily heats it up to the required high teinperature.

To cause the apparatusto work regularly, the amount of liquid hydrocarbon fed to the vaporizing-cylinder must be in proportion to the volume of vapors passing to the burners by the pipe D, and the pressure in the cylinder must be constant, and for this purpose the valve shown in Fig. 3 is interposed be2 tween the liquid-hydrocarbon-supply pipe (the oil in which would be under a suitable-- the supply side of the valve L exceeds that- IOO in the cylinder A, it opens and pressing on the valve-stem k presses K onto its seat,

thus closing the valve and passage for hydrocarbon, except by way of the grooves 7c, tothe cylinder. On the other hand, if the pressure in A exceeds that on the valve L the lower valve K is raised from its seat, so closing the valve L and shutting E the supply of oil until the pressure in C again becomes greater than that iu the cylinder. The oil then passes into the cylinder and is vaporized and passes through the several compartments between the plates b and becomes thoroughly gasied under the influence of the high temperature therein. If carbon or coke be deposited, it is deposited on the plates and shafts and inner surface of the cylinder A, and after lengthened use of the apparatus a cylinder can be-cut off by closing the valves d and h or d h of this cylinder and cleaned by opening out one end cover a, while the other cylinder can be in action.

As' will be seen by the drawings, all th burners will be fed byvapor from either of the cylinders A, and consequently they are operative no matter which of the cylinders is inaction.'

The' burners Y are of a special kind and are specially constructed to prevent their I becoming dirty or greasy or their regulating devices becoming choked or jammed owing to the high temperatures to which they are subjected, as happens'with burners hitherto proposed. ITo obviate these difficulties, the valve-box N is provided with a hollow nozzleplug M, screwed into N, withoue or more holes in its end, the length of the holes being very short, as shown,'and are in-consequence not likely -to clog and can be easily cleaned.

The inner edge of 'the hollow plug M constitutes a` seat, in connection with which a broadtaper'ed valve O on the end of a valvespindle o works,`.which valve-spindle passes through a stuffing-box P, having within it aseparate gland' p, 'and the stem o" is screwed outside' this'gland'and is therefore out of contact with the heat and in a cool part, so that elogglngof the'screw is avoided,as thescrew l l is kept away from the vapor and heat.

The burners may be arranged as shown in ing a D-shaped vessel with the loweredges of the divisions B standing above the floor, while the floor of the retort itself is ribbed, as shown, transversely.

The apparatus may be started by heating up the cylinder by ordinary lighting or by burning spirit or the like under it, and it may be charged withvolatile spirit, which starts it, andwhenhot' enough the heavy hydrocarbon' liquid is turned on.

The invention is not limited to the form of details,and sometimeslonly use one cylinder.

What I claim in respect of` the herein-described inventionisl. In apparatus for heating steam-generator or other furnaces by oil-gas, a 'pair'of oilvaporizing cylinders A, with internal diaphragms b carried from a central spindle B; and oil-inlets and vapor-outlets for said cyl inders; substantially as and for the purposes set forth. 2. In apparatus 'for heating steam-generator or other furnaces by oil-gas, theoil-vapon izing cylinders- A, with internal diaphragme b, and threaded shaft B carrying said dia-l at one end, .and vapor-outlet' pipe D ati-the opposite end; substantially as s'et forth.

3. In `apparatus for heating steam-generator or other furnaces by oil-gas,` the oil-vaporizing cylinder A with internal diaphragms b, and the threaded shaftB., carrying said diaphragins and on and by which they can be adjusted longitudinally, and oil-inlet pipeC at phragms, and on and b'ywhich -they calf be adjusted longitudinally; .and'oil-inlet pipe C one end, and vapor-outlet pipe d at the oppon site end; substantially as set forth.

In testimony whereof :Ihave hereunto set my hand in presence of two subscribing wit-` nesses.
